vb.net中如何获取当前日期所在星期的星期一

1

string[] Day = new string[] { "星期日", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六" };

string week = Day[Convert.ToInt32(DateTime.Now.DayOfWeek.ToString("d"))].ToString();

this.lbDay.Text = week;

2

this.lbDay.Text = System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetDayName(DateTime.Now.DayOfWeek);

vb.net中如何获取当前日期所在星期的星期一的具体年月日

Dim ThisDay As String = Format(Now, "yyyy-MM-dd") '获得当前日期字符串

Dim ThisDateTime As DateTime = Convert.ToDateTime(ThisDay) '当前日期转换成DateTime

Dim ThisWeekDay As Integer = ThisDateTime.DayOfWeek '获得当前日期是星期几

Dim differadd As Integer = 1 - ThisWeekDay '相差的天数(星期1与当前星期几相差的天数)

Dim MyAdd As New TimeSpan(differadd, 0, 0, 0)

Dim MyYear As Integer = Format(Now, "yyyy") '获取当前日期的年份

Dim MyMonth As Integer = Format(Now, "MM") '获取当前日期的月份

Dim MyDay As Integer = Format(Now, "dd") '获取当前日期是几号

Dim MyToday As DateTime = New DateTime(MyYear, MyMonth, MyDay)

Dim Yourday As DateTime = MyToday.Add(MyAdd)

MsgBox("本周星期一的日期是:" Yourday)

用基于vb的asp.net编写显示当前日期时间和星期几的代码怎么写?急用

C#

string [] Day=new string []{"星期日","星期一","星期二","星期三","星期四","星期五","星期六"};

Console.WriteLine(Day[Convert.ToInt16(DateTime.Now.DayOfWeek)]);

相信VB.net的你,应该懂的。
